Antigravity Jules Integration

Jules for Antigravity

[](https://marketplace.visualstudio.com/items?itemName=antigravity-platform.antigravity-jules-integration)

Jules for Antigravity is a powerful bi-directional bridge that connects your local coding agents (like Antigravity) with Google Jules, an advanced autonomous remote coding agent.

> 🤝 Bridging Local Agents & Cloud AI: This extension allows your local agents to "phone a friend" by delegating complex, long-running tasks to Jules in the cloud, while maintaining full context of your local workspace.

> [!NOTE] > Compatibility Notice: This extension currently requires Antigravity to function. A standalone VS Code version will be released soon.

Features

• 🚀 Two-Way Agent Bridge: Enable local agents to programmatically start Jules sessions via MCP (Model Context Protocol).
• 🧠 Automated Context: Automatically gathers active files, Git diffs, and Antigravity artifacts to give Jules full context without manual uploads.
• ⚡ Lazy Loading: Efficiently loads session logs on-demand to save bandwidth and API quota.
• 🚦 Robust Quota Management: Intelligent retry logic with exponential backoff handles API rate limits automatically.
• 🔄 Bi-Directional Sync: View Jules' thought process in real-time and apply changes directly to your local Git branch.
• 🛡️ Secure: Uses VS Code Secret Storage for API keys and sanitizes all error messages.

Installation

1. Install Antigravity IDE or the VS Code extension.
2. Search for "Jules for Antigravity" in the Extensions view.
3. Click Install.

Configuration

Before you can start sessions, you must configure your access credentials.

1. Prerequisites

• Install the GitHub App: You must install the Jules GitHub App on the repositories you wish to use.
• Enable the API: Ensure the Jules API is enabled in your Google Cloud Project.

2. Get Your API Key

1. Go to the Google Cloud Console Credentials Page.
2. Create a new API Key (or use an existing one).
3. Copy the key string (starts with AIza...).

3. Add Key to Extension

1. Open Visual Studio Code.
2. Open the Command Palette (Ctrl+Shift+P or Cmd+Shift+P).
3. Type and select Jules: Set API Key.
4. Paste your API Key and press Enter.

> 🔒 Security Note: Your key is stored securely in the local operating system's Keychain/Credential Manager using VS Code's SecretStorage API.

Usage Guide

1. Manual Handoff ("Click-to-Run")

Perfect for when you want to delegate a task yourself.

1. Open the Jules Orchestrator panel in the Activity Bar.
2. Click + New Season.
3. Type your Mission Brief (e.g., "Refactor the auth middleware to use the new JWT library").
4. Click Start Session.

• Context (files, diffs, plans) is gathered automatically.

2. Agentic Handoff (The Bridge)

Your local Antigravity agent can call Jules directly:

{
  "tool": "delegate_to_jules",
  "arguments": {
    "task": "Analyze the security of the payment module"
  }
}

This enables "Agent-to-Agent" collaboration, where your local assistant orchestrates larger goals by sub-contracting work to Jules.

Architecture

This extension uses a Hybrid Agentic Architecture:

• Local: Runs as a VS Code extension + MCP Server for low-latency context gathering.
• Remote: Connects to jules.googleapis.com for heavy-lifting autonomous coding.

For a deep dive into the internal components (BridgeServer, ContextGatherer), please read our [Developer Documentation](DEVELOPMENT.md).
